Carbonation of Granite Fines Concrete in the Tropical Environment
The exhaustion of major sources of natural sand in the region has provoked the use of alternative materials for sustainable concrete construction. Granite fines (GF) has been encouraged in many countries, including Singapore, to replace natural sand in concrete mixing. Carbonation is one of the most detrimental durability problems that cause the deterioration of reinforced concrete in the tropical countries like Singapore. However, the effect of GF replacement on the carbonation resistance of concrete is not well understood at present. The objective of the current work is to understand the effect of substituting natural sand with GF on the carbonation resistance of concrete in both accelerated and natural exposure condition. This study conducted a series of carbonation tests in both accelerated testing condition and natural exposure condition, on concrete produced with 0, 50, and 100% of granite fines substitution. The test results demonstrated that the replacement of natural sand with GF can enhance the carbonation resistance of the concrete. This study also established a correlation between the accelerated testing condition and natural exposure condition. The findings of this research provide recommendations on the service life design for industrial projects and may be further incorporated in design codes of the region.
